Pretty hard to top Shanghai's People's Square.

Not a fan of the transfer at Dongzhimen in Beijing for the Airport Express Line either.

I was impressed with the transfers coming from XIY heading to my hotel by the South Gate. Two very smooth transfers similar to the platform crossover at Guanglan Rd in Shanghai. (Not quite the same heading to XIY).

Here in Harbin, we only have one transfer station but hopefully at least 2 more will be online in a moth or so.
